SQL Views Tutorial | VIEWS in SQL Complete Tutorial

The first 1,000 people to use this link will get a 1 month free trial of Skillshare: skl.sh/techtfq02221
This is the SQL VIEWS Tutorial video, where I explain VIEWS in SQL in detail. We cover everything you need to know about SQL VIEWS and how to effectively use SQL Views.
The video starts by explaining what a View is and how different it is from a table. We then look at how to create a View and also explain in detail the purpose of using a view in sql. We talk about the advantages of views in sql and why we use views in SQL.
We then see how to create a view using CREATE OR REPLACE command and how different it is from just the CREATE VIEW command. I mention in detail all the rules you need to know when using CREATE OR REPLACE command.
We also see how to modify a View using the ALTER command.
I also mention some tips and tricks about Views that can be essential to clear interview questions related to Views.
At the end of the video we look at updatable views i.e. the views which can be updated or inserted or deleted. We look at the different rules we need to follow in order to create a view which can be updated.
Finally we talk about the WITH CHECK OPTION clause when creating a view. We understand why we use WITH CHECK OPTION clause and how is it useful in certain cases.
The only VIEW concept not covered in this video is about the Materialized View. I will be making a separate video about Materialized View very soon.
Hopefully this video should give you complete understanding about VIEWS and how to effectively use VIEWS in SQL.

Hi Taufiq, I have recently revised SQL using your videos. This is an appreciation comment. I am so happy that I discovered your channel. The concepts are way more clearer now. all videos were easy to understand but special mention to Joins,cte and windows function are the best videos to refer to. I have made hand written notes while revising them. I feel more confident now. Now all I have to do is practice, practice ,practice. Going to suggest people to definitely stop by your channel and learn. Kudos to your hard work and knowledge.

[@techTFQ]

Thank you so much Nishtha 🙏 Super happy to read your comment and good luck with the practice 👍

[@sushantkumar8208]

Hey, if you don't mind, can you share those notes? It will be really helpful.

Hello Taufiq, I just wanted to take a moment to thank you for the excellent SQL tutorials you've been creating.

[@rahulvalecha6425]

Hi Thoufiiq, First of all, thank you very much for the amazing content. I was trying to practice all the things which you taught in this video related to views and i realized that some of the rules does not apply in MSSQL . For e.g. 1. You can change the order, column name, etc in view. But I guess that is because we use to create or alter command as there is no replace statement. 2. I was able to update data through view even though I was using joins in my view. Just wanted to share my findings. Waiting for videos on materialized views.

[@techTFQ]

Thanks for sharing it Rahul.. yeah some differences in other RDBMS .. will cover materialized views soon

[@mritunzaysingh8978]

Please check one more time If you make some updates with join in view then please check there are some changes have made on base tables because if you update view which based on 2 tables then it mismatched the data in both the table.... I think that is why we use triggers

[@shivampatel6044]

Rules are differ from one dbms to another dbms. Even i have the same query initially.

[@arindamsaha1929]

in second point which you mention you are able to update a view where you use join, i think you are update those column which is present in one table , if you want to update a view which has column from multiple table then you got an error to tackle those situation we have insted of trigger. please correct me if i'm wrong.
